I will be keeping an eye on this thread to see what other people do, but what I have done in the past is to have a couple different health checking strategies.

• For web-accessible services I am running, I usually run something like Uptime Kuma or Gatus on a different box checking to make sure those web endpoints are available and performant. I lately have been really digging how Gatus can check more than just the response header, but also latency and certificate validity.
• For the host machine, you can set up custom alerts within netdata for stuff like cpu utilization and memory with custom thresholds. The only other solution I have used for this in the past is setting up alerts through my VPS provider (if it is a VPS that is).
  • On really low-spec machines I have had trouble with netdata though, so I don’t have a good solution in those cases. Interested to see if there are less demanding options. Instead, I have resorted to just using dashdot as a PWA so that I can check it easily on my phone if I am on the go.
• For some custom services in the past that run on set schedules, I have used healthchecks.io (which you can selfhost) to send alerts in the case that they don’t run for some reason.
• As for the containers being restarted, I actually don’t have experience with that, so I am interested to see what others have done.

This isn’t really an answer, but I spent a lot of time trying different voice chat systems out a couple years back, but couldn’t get my social group to move off Discord.

So, the real answer is any that you can convince the people you want to talk with to use. However other options include Mattermost, Jitsi, Mumble, Teamspeak, and Nextcloud Talk off the top of my head. I think I remember seeing that rocket.chat has voice now too.

I have a Brother MFC Color Laser and everything here is true for the color version as well. I haven’t had too many issues with wifi jank after I set a static ip both on the router side and the printer side, and then map the printer by ip port on the computer. However, it still acts up every now and then. I plan on fishing some ethernet to that corner of the office, but haven’t gotten around to it yet.
